BS 5266-5:1999 specifies requirements for optical fibres, lightguides, connectors, emission end mounting arrangements and light sources to be used in optical fibre emergency lighting systems. Constructional and performance requirements are given, including performance under fire conditions.
The standard is applicable to the component parts of an emergency lighting system using optical fibre lightguides to distribute light from a light source to one or more lighting positions remote to that light source.
The standard specifies the use of optical fibres with end illumination and end emission. It is not applicable to optical fibres with end illumination and side wall emission.
NOTE. This Part is to be used in conjunction with BS 5266 : Part 1 and BS 5266 : Part 4.
